Psychological characteristics of students who received the highest ratings in both student and professional teaching were examined and compared to those of students who rated the lowest in both fields. Although the resulting profiles from the two groups did not differ significantly, trends indicated that the more successful group had a good self image and were poised and self assured. The less successful teachers, although seemingly more independent, tended to score lower on measures of trust, self control, and responsibility. Capsule descriptions of the personality traits examined are appended. (Author/CJ)
